It has 2 USB charging ports, One rated at 1.0amp and the other 2.1amp there is an easy to read LCD screen and one LED that you can turn on or off via a switch.

For what I have in mind for this power bank I think this is the best option for me.
P.S. I will be using this 5000mah Power Supply, to power my Xiaomi Mi WiFi Extender so I can control my DJI Tello

A review of the Efan X6 Charger. It has 6 bays and you can charge at 0.5A, 1A, 2A or 4A depending on what bays are in use! With a beautiful and bright LCD screen, and affordable price, this charger is great for everyone!
